Building an Android، iOS app, or stuck with one that's broken? Before I give you a number, I want to look at what you already have. The code, the designs, the crash reports, a screen recording of the bug, whatever exists. Half the time the problem isn't what someone was told it was. I'd rather find that out in the first two days than in week three. So send me the app, the Figma file, or just a description of what's going wrong. You'll get an answer within a day: what I think is actually happening, roughly how long it takes, and whether it's worth doing at all. If it's not something I should be the one building, I'll tell you that. I'm a senior Android developer. Four years of it, across telecom, fintech, e-commerce, streaming and TV. Most recently at Vodafone Egypt, before that e-finance and Mtor. Some of what that looked like: A payment module at Vodafone that was quietly failing about a fifth of its transactions. Found it, fixed it, transaction success went up 20% on an app serving 50M+ users. Crash rate came down 15% and load time 10% over the same period. An app at e-finance that was 80MB. Got it to 38MB. Downloads went up 25%, mostly from people on slower connections who'd been giving up on the install. Two e-commerce apps built from scratch at Mtor with Jetpack Compose, plus courier and supplier apps on a reactive MVVM architecture, with Firebase and Bitrise CI/CD behind them. A live streaming app I built on my own, with real-time video, in-app games, digital gifts and in-app purchases. A Flappy Bird-style game running on Android, iOS, desktop and web from a single Kotlin codebase using Compose Multiplatform. On Upwork specifically: an Android TV app in Kotlin, a Jetpack Compose performance bug nobody had been able to pin down, a web scraping Android app, and an Android payment terminal build. I work in Kotlin and Java, Jetpack Compose, Android SDK and Android Studio, Flutter for hybrid and cross-platform builds, and Kotlin Multiplatform when a project needs Android and iOS from one shared codebase. Clean Architecture, MVVM, Coroutines and Flow, Retrofit and Ktor, Firebase, Room, Hilt, REST APIs, unit testing with MockK. I've mentored seven Android interns; two of them got hired full-time. The thing most clients are actually worried about isn't whether the developer can code. It's whether he'll go quiet, or hand back something the next person can't maintain. I write code the next person can read, and I tell you early when something's going to take longer than I said. Top Rated on Upwork with 100% Job Success. Tell me what you're building, or what's broken.
